Ground based Fourier Transform Infrared (FTIR) measurements have been performed at the Arctic Station of Ny-Ålesund, at the mid latitude site Bremen, as well as on board the German research vessel Polarstern. Additionally, aerosol and ozone lidar measurements were conducted and ozonesondes have been launched at Ny-Ålesund. Here, we give an overview of the data recorded so far, and show first comparisons of the data with Sciamachy products.
